The compatibility of RAM modules with your computer is crucial to ensure optimal performance. Your PC's motherboard supports only a specific type of RAM, such as DDR4 RAM, DDR3 RAM, DDR2, or others. For example, if your computer is equipped with DDR4 type modules, you'll need to opt for DDR4 modules when adding or replacing memory.
The simplest solution is to purchase identical modules to those already installed. However, to precisely determine the RAM format of your PC, several methods are available:
-
Check the manufacturer's official documentation: Refer to your computer's specifications provided by the manufacturer. You'll find information such as the number of available slots, the number of modules already in place, and the supported RAM format.
-
Use third-party software like CPU-Z: You can download and install software like CPU-Z to obtain detailed information about your PC's memory. These applications will provide precise data about the type of RAM installed.
-
Use Windows PowerShell: You can also access RAM information using Windows PowerShell. Type the following command: Get-WmiObject Win32_PhysicalMemory | Select-Object SMBIOSMemoryType. This command will give you a code corresponding to the format of the installed RAM, for example, 26 for DDR4, 25 for DDR3, 24 for DDR2, and so on.
-
Module Timing (Latency): Timing, also known as "latency" or "CAS latency," is a crucial technical data. It expresses the number of processor clock cycles required to access data stored in RAM. In other words, latency indicates the time it takes for your computer to retrieve and display information stored in memory. This latency is usually represented by a series of four numbers. The lower these numbers are, the lower the RAM latency, meaning it's faster. However, it's important to note that lower timings may increase the cost of the module.
-
Required Electrical Power: Another criterion to consider is the voltage at which the module must operate, expressed in volts. If a module requires low voltage, it means it consumes less power. It's important to check if the voltage required by the module matches that supported by your computer's motherboard. Voltage incompatibility can lead to compatibility and performance issues.
In summary, RAM compatibility with your computer is a key factor for optimal performance, it's preferable that all modules have the same frequency, as the system can only use the lowest frequency among those installed.
If a module operates at a lower frequency, it will run at a lower speed constantly, resulting in a loss of resources and suboptimal performance.
But don't neglect other important features such as timing, required electrical power, and avoid common errors when purchasing RAM.
Taking into account all of these criteria will allow you to get the most out of your computer in terms of speed and reliability.
